The Evolution of Pre-Christian Nordic Religion

Compared to many cultures around the globe, very little evidence remains of pre-Christian religious beliefs and practices in Scandinavia. By far the best known pre-Christian temple in Scandinavia was the temple in Uppsala, having been attested to in the writings of Adam of Bremen. However, evidence remains scant. Some archaeological evidence of a hall near to the burial mounds of Gamla Uppsala has been uncovered but, because of the decay of building materials, very little evidence remains to be interpreted. These remains have largely been read as being evidence of a hall where both political and cultic practices may have occurred, including sacrificial feasts (1) though some have suggested that this may have been the temple, or served both functions.(2) Even the best known religious sites offer us little evidence to interpret or develop an understanding of Scandinavian religions prior to the conversion era.

Considering the minimal nature of archaeological evidence of pre-Christian religions in Scandinavia, how do we know what we know about those religions? “Apart from the rune stones, contemporary written information about the Viking homelands is almost exclusively the work of foreign clerics,” Else Roesdahl notes in The Vikings, “few of whom had visited Scandinavia. Nearly all these texts are in Latin and they were usually written following political or military confrontations on Denmark’s southern border, or attempts to convert the pagan northmen to the true Christian faith.” (3)

Most of what we think we know about Scandinavian religion before the arrival of Christianity is, in fact, based on writings from contemporary Christian clergy. Yet the history of complex religious beliefs in Scandinavia was established long before the onset of the best-known and best-evidenced eras of Scandinavian history, the Vendal and the Viking eras, let alone before the arrival of Christianity.

Evidence of religious beliefs in Scandinavia dates to as early as the Stone Age. “The Stone Age archaeological record paints a surprisingly complex picture,” writes Bryon J. Nordstrom. “Artifacts of bone or amber and petroglyphs and pictographs, such as those in Alta in Norway or the somewhat later ones at Nämforsen in southern Sweden, depict reindeer, moose, bear, birds, fish, whales and humans. These depictions indicate the presence of animist religious beliefs from very ancient times.” (4) Based exclusively on the archaeological evidence we can see an evolution in these animist beliefs (defined primarily by a belief that all things in nature contain a spirit, not just humans). In the late Mesolithic, for instance, occurs new “systematic burial practices that may indicate a belief in an afterlife or veneration of family members.” (5)

This late-era shift in religious practices and beliefs lead to the new practices of the Neolithic age, shifting toward a religious outlook which favored ancestor veneration and practices regarding death and belief in the afterlife. This is evidenced by megalithic graves, dolemens and passage graves. (6) Because of the obvious amount of labor and time expended upon the construction of these graves and because they were used repeatedly, there is a strong likelihood that such grave sites doubled as cult sites.(7)

We come next to the Bronze Age. The tradition of petroglyphs had certainly survived through the ages, the changes in climate, and invasions. By this point in history “the most common images are of ships, circles and wheels, men with weapons, men with exaggerated phalluses, plows, footprints, and occasionally women…they may be sacred images, including the sun, the ships that carried the sun across the sky, and gods and goddesses of the hunt, the field, and fertility.” (8)

Moving into the Migration and Vendal eras, we continue to have a wealth of archaeological evidence up for interpretation. This evidence continues to come from places of burial and sacrifice and, just as the cultures of these ages “may also be seen as direct antecedents to the Viking Age,” (9) it seems reasonable that the religious beliefs of these ages were also direct antecedents to Viking Age religion. This is especially true when we consider that the only thing directly separating the Vendal and Viking ages are the written records of the Viking invasions of Lindisfarne in 793. (10)

At long last, the beginning of the written record regarding Scandinavia has begun. Because of the great wealth of churches, which housed the aforementioned literate clergymen, Vikings often targeted them. Though they had not yet begun to write about the religion of the Vikings, this marks the point at which the written record can be used to corroborate theories about the archaeological evidence which, in regard to religion, continues to remain inconclusive. Stone carvings continue to be an important source of evidence, such as the picture stones in Gotland dating between 400 and 800 A.D., which depict “sailing ships, costumes, processions, battles, sacrifices, and Norse gods such as Odin.” (11) Though these are among our primary sources of evidence, in addition to grave goods and sites of sacrifice, it is worth noting that “pictures can rarely be interpreted precisely, but they give an impression of ceremonies and rituals and also confirm some of the stories about the gods…” (12)

Though it is far simpler, it is neither wise nor advisable to entirely separate these different periods of religious belief from one another. The evolution of religious practices and beliefs is just that—an evolution. These beliefs and practices evolved in tandem with the society out of which they arose. We can see in the Stone Age that animist religions underwent a change as the people themselves shifted from the nomadic lifestyle of the Megalithic age to the settlement lifestyle of the Neolithic. I would argue that the more familiar beliefs of the Viking age could not and would not have taken the shape they did if it weren’t for the shape these earlier religions took and the effect changes in society had on their development and evolution, much like modern people could not exist in their current form without their ape ancestors.

Some disturbances naturally occur which induce or alter this process. These included changes not only in climate but also invasions which brought new people with new weapons, technologies, and cultures, as well as new religions and new gods:

“Some researchers believe Sweden, along with much of the south Baltic, Denmark and Finland, were invaded by nomads whose origins lay along the western slopes of the Ural Mountains…some archaeologists think they brought with them the prototype of the later Germanic languages, including Swedish, and a new set of gods. According to this interpretation, these invaders descended on the peasant farmers of the north, conquered them, became a new elite, and erased the old cultures. Good evidence supports these views: The beautifully crafted boat-shaped ceremonial axes, crudely decorated pottery, and simple individual chamber graves become common and were strikingly different from their counterparts in either of the older Neolithic cultures.”(13) 

Though it is true that these invading forces re-shaped the existing culture, it is drastic to say that they could or would have utterly eradicated it, as is suggested when Nordstrom writes that the invaders “erased the old cultures.” While significant damage to existing cultures can and is often done when a foreign force invades an area, historically this often involves some degree of assimilation rather than total annihilation. We can see this in other instances of invaded peoples straining to retain their culture and new rulers making certain cultural concessions to keep their newly conquered people in the fold.

With specific regard to religious practice and belief, there are plenty of examples of religions meeting wherein the conquering religion assimilated rather than destroyed the other. Take, for example, the Greek Titans: some scholarship suggests that these formidable beings in Greek mythology represent deities from an older religious tradition. This argues that the depiction of the Titans as having been conquered and imprisoned by a younger generation of gods represents a newer religious tradition supplanting the elder. This is a mythological form very closely mirrored in other cultures, including the Babylonians, Hittites, and Phoenicians.(14) Lotte Motz highlights specific examples: “The Giants and the Titans of the Greeks were ultimately defeated by Olympic Zeus; the great god Marduk of the Babylonians opposed those from whom he was descended, who were fighting under the leadership of Kingu.” (15)

I propose that we can see echoes of this myth-form in the war between the Nordic Aesir and the Vanir, as well as the ongoing struggles between the Aesir and the Jötnar. Multiple waves of migration into Scandinavia followed closely by discernible shifts in religious orientation, values, and structures may very well indicate that a series of invading and supplanting cultures introduced a series of supplanting religions. This is in addition, of course, to other environmental factors that were prompting changes in religious focus and values, such as the switch from nomadic lifestyles to settlement lifestyles, often corresponding with a switch between hunter-gatherer cultures and agricultural cultures.

Ultimately while it is hard to definitively interpret the archaeological evidence without textual evidence to fill in the gaps, we can make reasoned assessments based on the evidence we do have. We can additionally study the evolution of other, better documented religions around the world to fill in our understanding of the kinds of patterns and changes that are common in religious evolution. Taking the evidence we do have and comparative studies of comparable myth-forms and religious developments from the around the world, it’s not such a stretch to interpret the primal, often clearly nature-associated jötnar as survivors of an older, primordial animistic religion that set the stage for later Nordic religions.

Christian Bias in the Surviving Lore 1

I’ve touched on the fact that the surviving lore is heavily influenced by Christian forces that had already began to shape the Nordic world and the world at large by the time the lore was recorded. There is much to be said on this topic, but it is worth acknowledging first and foremost that many if not most of those practicing Rökkatru were raised in a dominantly Judeo-Christian culture. Much of the “western” world (read: Europe and the Americas) have been heavily shaped by Christian imperialism, be that Protestant or Catholic (or both at different points in history).

However much many American and European pagans seek to distance themselves from their own Christian pasts and the Christian legacy of their national identities, it is not possible for anyone to completely divorce themselves from the effects of the culture that they were raised and socialized in. It is for this reason that many neopagan practices mirror Christian and Catholic practices, especially with regards to theologies hinging on the idea of “good” and “evil.”

It is worth noting that there is nothing inherently wrong in having been subject to this influence—again, we all have to some extent. Just as it is impossible to grow up in an inherently white supremacist culture without internalizing some degree of racial bias, so it is similarly impossible to grow up in a culture so shaped by Christian theology and not internalize that values system to some degree. The best anyone can do is educate themselves about those influences and reflect on the way those cultural and societal pressures are effecting their own patterns of thought, belief, and practice.

The purpose of the following sections is to provide some rudimentary historical education on the Christianization of the lore. With that educational basis it becomes a lot easier to reflect on the way these forces have shaped our own belief structures and worldviews, but that work (and whatever conclusions you come to in that process) will be yours alone.

Adam of Bremen


There are two major players in the way Christianity shaped our knowledge of old Nordic religious beliefs and practices. I’m going to start with an analysis of the writings of Adam of Bremen, whose writings predate Snorri Sturluson’s by approximately 125 years. His are among the most important writings regarding the religion of the Vikings and includes an account of the temple in Uppsala written c. 1075 A.D.

In his famous description of the temple of Uppsala and the rituals that occurred there, Adam describes a temple which housed pagan idols where, every nine years, the kings of the land gathered to pay homage to the gods. All their people were to send gifts of offering and sacrifice. No one, he noted, was exempt from this duty.

During this time a sacrifice was made consisting of nine “of every living thing which is male…with the blood of which it is customary to placate gods of this sort. The bodies they hang in the sacred grove that adjoins the temple. Now this grove is so sacred in the eyes of the heathens that each and every tree in it is believed divine because of the death or putrefaction of the victims.” He does, however, go on to relate how this information was passed on to him second hand, namely by “a Christian seventy-two years old” who had witnessed the sacrifice, a detail which reminds us that Adam of Bremen never himself witnessed these rituals or laid eyes upon the temple. Furthermore, we are made to understand that some portion of what was related back to him was not, in fact, preserved in his writings, as he states: “…the incantations customarily chanted in the ritual of a sacrifice of this kind are manifold and unseemly; therefore, it is better to keep silence about them.” (1)

Of course, by the time of Adam of Bremen’s writing, Christianity had a solid presence in Scandinavia. In fact, a great number of the stories he writes in regards to paganism in Scandinavia are stories about Christians fighting the evils of paganism either by attempting to convert the people, destroying idols and places of worship, or simply plotting to do so. It is reasonable to assume that “the temple, priests and statues may all have been influenced by Christian worship, for they are not known from earlier sources” (2) and evidence of the existence of temples in pagan Scandinavia remains scant to nonexistent.

Nonetheless, aside from place-names, which can point us to cult places and locations where certain gods were popular among the locals, (3) we have little evidence outside of Adam of Bremen’s account about what religious ceremonies and rituals in the Viking era looked like. This makes his account incredibly valuable though we must read it with approximately a quarter pound of salt because 1) Adam of Bremen never himself visited or laid eyes on the temple at Uppsala. His account is based on the stories of those who had. Furthermore, 2) his bias as a member of the Christian clergy undoubtedly colored his perception of these ceremonies and rituals and therefore colored his descriptions of them (as is evident where he chooses to omit details about the rituals).

What kinds of conclusions can we then draw from Adam of Bremen’s account? It seems reasonable to assume that the pagan religion of the people of Scandinavia was relatively malleable and capable of adaption if, as scholar Else Roesdahl suggests, the building of the temple and the incorporating of priests was the result of contact with Christianity. Likely because the pagan religion was a polytheistic one there was little perceived threat from the appearance of the Christian god, as the existence of this god and the fact that he was worshiped by these newcomers would not have drastically altered their view of the world in terms of religion and their own relationship to the divine—if there are a plethora of gods, after all, why should one more be so surprising?

From Adam of Bremen’s account we further know that the use of idols was practiced by the pagans of Scandinavia—something which can be corroborated by archaeological evidence—and that sacrifices of life and blood were performed in the presence of these idols to pay homage to the gods they represented. Archaeological evidence of various kinds of sacrifice in the pagan religion of Scandinavia has been found throughout the land, including the so-called “Bog People” in Denmark, which “appear to reveal…the presence of a religion devoted to fertility, in which humans were sacrificed to secure an abundant harvest.” (4) Though very little if any evidence has been found at Gamla Uppsala to support Adam of Bremen’s assertions of sacrifices which included humans, this cannot be discounted entirely given the incontrovertible evidence that human sacrifice was practiced elsewhere in pagan Scandinavia.


One of the most famous of the “Bog Bodies” is known as Tollund Man. He is famous for the heightened degree of preservation, including preservation of his clothing and the noose around his neck.

In addition to offering up blood to the gods, we also know that practitioners offered up incantations to accompany their sacrifice, though once again what those incantations are must be relegated to the realm of theory, imagination, and possibly UPG/PVPG. Because of Adam of Bremen’s refusal to record them due to their “unseemly” nature, we know these incantations run counter to his own Christian faith. This doesn’t, however, tell us overly much as this could simply be a reflection of the unseemliness of the worship of “false gods” in his eyes, or it could allude to incantations relevant to fertility, and perhaps the sexuality inevitably involved in matters of fertility. Adam of Bremen could have chosen to exclude these “unseemly” incantations for any number of affronts to the Christian religion, and it is impossible to know which of Christianity’s laws were broken or in what way those laws were being broken in these incantations without having access to them.

Depictions on various rune stones together with Adam of Bremen’s account of the activities at the temple of Uppsala give us an idea of what religious practice may have looked like in Scandinavia both during the time of conversion and the time shortly preceding conversion. Aside from telling us that the people engaging in these practices believed that they could please the gods to achieve some worldly purpose, the practices themselves don’t shed much light on the beliefs. To learn more about the beliefs themselves, we will turn in the next post to records of the myths of pagan Scandinavia, the most important of which being Snorri Sturluson’s 13th century The Prose Edda (5) along with the works upon which Sturluson based his Edda. These are the most known and most heavily relied upon sources for the majority of modern heathen practitioners, so stay tuned for a close reading of them.
